perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hello;

Unfortunately the perfSONAR tools (BWCTL, OWAMP) that would participate in a 
regular testing fashion will not work with NAT.  In most cases the tools need 
to bind to a specific address as a part of their protocol operation.  

There are ways to work around this on the command line, for example BWCTL can 
function if one end of the connection has a non-natted address.  There is an 
option called —flip that will reverse the direction of the control protocol 
to enable communication.  OWAMP will not be able to work with a NAT due to 
the way it is designed.  

To address the last issue, we do not have an IRNC channel.  

Thanks;
